1937, Serial No. 135,275. In Great Britain 6 Claims.

The present invention is a divisional application of my application forMethod and apparatus for making containers, Ser. No. 678,133, filed June29, 1933, which is a continuation in part of my co-pending patentapplication, Ser. No. 629,007, filed August 16, 1932.

The present invention has for its object improvements in containers andmore particularly in containers. or tubes deformable by compression andcontaining fluid, viscous or pasty material.

According to the present invention, a container of the kind referred tocomprises a movable closure member or stopper fixed at the extremity ofthe container, of which the material is pressed or extruded around it,and provided with an exterior finger or member for manipulative purposesallowing of its being displaced and for example of making it turn toopen or close the con- 30 tainer.

According to one way of carrying out the invention, the closure memberhas an open dispensing portion which may be brought into register withthe prolongation of the neck or orifice of the container, when thislatter is to be opened, or be angularly displaced so that the body ofthe closure member covers the said neck or orifice and ensures theclosure.

Further features of my invention relate to a novel type of closure meansadapted to serve as a stopper in connection with a cork or otherwise forany container, such as a bottle, etc., being provided with two vents forthe free and rapid discharge of fluid therefrom.

The following description, with reference to the accompanying drawingiven by way of example, will make the improvements easily understood.

Fig. 1 is a vertical sectional view of an embodiment of my inventionhaving an air inlet vent to secure a rapid delivery of liquid from themouth of the bottle thereof.

Fig. 2 is a side elevation of the closure means employed in Fig. 1.

5 I provide a nozzle closure means for necks or nozzles of liquidcontainers having a movable closure member oscillatable within saidnozzle from an open position to a closed position to dispense the fluidtherein, which is] formly re- 0 tained in the nozzle, the metal of thenozzle itself being pressed around the outer end of the closure member.

As shown in Figs. 1 and 2 my invention may be applied to a bottle, inwhich case the stopper 5 d is inserted as usual in the neck 11, thelower July portion 112 of which may be suitably mounted within asuitable cork n forming the stopper for the bottle a If desired the neckor nozzle b may be provided with the supplemental outwardly flaringflange 0 adapted to rest on the upper end of the bottle neck t. Inaddition to the fluid discharge vent e a supplemental air inlet R ispro- Vided to admit air within the bottle therethrough as the liquid isbeing withdrawn out through the outlet e, thereby providing a closuremember which will permit a rapid discharge of liquid from within thecontainer.

It is evident that modifications may be made in the devices abovedescribed, without departing from the scope of the invention.

What I claim and desire to secure by Letters Patent is:-

1. Closure means for containers comprising, a nozzle having a partiallyspherical recess therein and an inlet and outlet, a hollow, at leastpartially spherical closure member contained within said recess andhaving outlet vent means and a separate inlet vent means of a size toadmit sufficient air for rapid discharge of liquid through said outletvent means and a projection projecting outwardly through the'end of saidnozzle from said closure member to move the outlet and inlet vent meansthereof from a position in alignment with said inlet and said outlet toa closed position, said closure member having diametrically oppositesingle axis of oscillation forming means thereon, the wall of saidnozzle being integrally complementally shaped adjacent said diametricaxis forming means to cooperate to form therewith cooperating male andfemale single rigid axis forming means.

2. Closure means for containers comprising, a nozzle having a partiallyspherical recess therein and an inlet and outlet, an at least partiallyspherical closure member contained Within said recess and having outletvent means and a separate inlet vent means of a size to admit suflicientair for rapid discharge of liquid through said outlet vent-means and aprojection projecting outwardly through the end of said nozzle from saidclosure member to move the outlet and inlet vent means thereof from aposition in alignment with said inlet and said outlet to a closedposition, said closure member having diametrically opposite single axisof oscillation forming means thereon, the wall of said nozzle beingintegrally complementally shaped adjacent said diametric axis formingmeans to cooperate to form therewith cooperating male and female singlerigid axis forming means, and to extend over a portion of the outer endof said closure member to retain it in position within said nozzle so asto form an air and liquid-tight seal for said closure member.

3. Closure means for containers comprising, a nozzle having a partiallyspherical recess therein and an inlet and outlet, an at least partiallyspherical closure member contained within said recess and having outletvent means and a separate inlet vent means of a size to admit sufiicientair for rapid discharge of liquid through said outlet vent means and aprojection projecting outwardly through the end of said nozzle from saidclosure member to move the outlet and inlet vent means thereof from aposition in alignment with said inlet to a position in alignment withsaid outlet, said closure member having diametrically opposite dimplestherein, the wall of said nozzle being integrally complementally shapedadjacent said dimples to form integral projections fitting in saiddimples to form single rigid axes.

4. Closure means for containers comprising, a nozzle having a partiallyspherical recess therein and an inlet and outlet, an at least partiallyspherical closure member contained within said recess and having outletvent means and a separate inlet vent means of a size to admit sufiicientair for rapid discharge of liquid through said outlet vent means and aprojection projecting outwardly through the end of said nozzle from saidclosure member to move the outlet and inlet vent means thereof from aposition in alignment with said inlet to a position in alignment withsaid outlet, said closure member having diametrically opposite dimplestherein, the wall of said nozzle being integrally complementally shapedadjacent said dimples to form integral projections fitting in saiddimples to form single rigid axis of oscillation forming means andextending closely over a portion of the outer end of said closure memberto retain it in position within said nozzle.

5. An at least partially spherical closure valve member having axis ofoscillation forming means diametrically thereof, a turning lug at theupper end thereof, discharge vent means substantially at right angles tothe diametric axis of said axis of oscillation forming means and spacedfrom said turning lug, and supplemental separate air inlet vent meansextending therethrough.

6. An at least partially spherical closure valve member having pivotdimples diametrically thereof, a turning lug at the upper end thereof,discharge vent means substantially at right angles to the diametric axisof said pivot dimples and spaced from said turning lug, and supplementalseparate air inlet vent means extending therethrough.
